How to backup a MySQL database to file in PHP? [duplicate]

Other option than using mysql dump

The below is a tested php code to backup database in .sql file

<?php
ini_set("max_execution_time", 0);

$dir = "";//set path of folder where to save file
if(!(file_exists($dir))) {
mkdir($dir, 0777);
}

$host = ""; //host name
$username = ""; //username
$password = ""; // your password
$dbname = ""; // database name

backup_tables($host, $username, $password, $dbname);

function backup_tables($host,$user,$pass,$name,$tables = '*')
{
$con = mysql_connect($host,$user,$pass);
mysql_select_db($name,$con);

//get all of the tables
if($tables == '*')
{
$tables = array();
$result = mysql_query('SHOW TABLES');
while($row = mysql_fetch_row($result))
{
$tables[] = $row[0];
}
}
else
{
$tables = is_array($tables) ? $tables : explode(',',$tables);
}
$return = "";

//cycle through
foreach($tables as $table)
{
$result = mysql_query('SELECT * FROM '.$table);
$num_fields = mysql_num_fields($result);
//$return.= 'DROP TABLE '.$table.';';
$row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
$return.= "\n".$row2[1].";\n";

while($row = mysql_fetch_row($result))
{
$return.="\n";
$return.= 'INSERT INTO '.$table.' VALUES(';
for($j=0; $j<$num_fields; $j++)
{
$row[$j] = addslashes($row[$j]);
$row[$j] = preg_replace("#n#","n",$row[$j]);
if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
if ($j<($num_fields-1)) { $return.= ','; }
}
$return.= ");";
}
$return.="\n";
}


date_default_timezone_set('Asia/Kolkata');
//save file
$way=$dir.'backup-'.date('Y-m-d H:i:s').'.sql';
$handle = fopen($way,'w+');
fwrite($handle,$return);
fclose($handle);
echo $way;
}

?>

The above code will create a .sql file in the location you have set in the code.To backup data time to time say in every day you have to hit this php file after each day to do that in:

Linux

Use cronjobs

Windows

Use Windows task Scheduler

Good Luck
